In the HVAC industry, Ecodesign directives have forced OEM manufacturers to improve the efficiency of heat pumps during all seasons of the year.This means that heat pumps must work efficiently in different working conditions.Its efficiency, known as the seasonal coefficient of performance (SCOP), must be above certain limits or else the heat pump cannot be marketed in the EU.For this reason, variable speed compressors are becoming more and more popular in this market.Carlo Gavazzi's RVPM drive fits the requirements of this market, providing a compact and fully compatible product for use in heat pumps, both for the residential and commercial sectors.RVPM is a variable frequency drive that is specifically designed for scroll compressors used in heat pumps, industrial air conditioners, chillers, and also commercial walk-in coolers.This device is designed with sensorless vector control and can be used with BLDC, PMAC and IM motor types.It comes in two models, one that uses what is known as a cold plate and the other with a built-in heatsink.The cold plate installation design allows significant space savings in heat pumps.The reduced set of parameters required to configure the RVPM makes it easy to install.OEMs can get the compressor up and running in minutes as minimal setup is required.In addition, RVPM can control BLDC and PMAC compressors, as well as induction motor compressors, for easier integration with a wide range of compressors.Editorial Automatic and Instrumentation No. 539By Jose Ignacio Armesto QuirogaThe application and development of new technologies focused on the industrial sector focus on improving productivity and minimizing environmental impactThe modular and expandable WT5000 is Yokogawa's most accurate power analyzerThe contact analysis for conical wheels allows the calculation of the effortsInterview with Brenda Discher, SVP Business Strategy and Marketing Siemens Digital Industries SoftwareWe speak with Xavier Aliaga, Sales Director Iberia Business Systems at Epson;and Jose Mª Sitges, technical director of SinergesEmail info@automaticaeinstrumentacion.com© Copyright 2021 - automaticaeinstrumentacion.com |All rights reserved
